To better apply obligatory decorators like db_session_cleanup, this
commit moves dcmanager and dcorch DB functions to a class. A follow up
commit will move db_session_cleanup to a class decorator and add this
commit hash in .git-blame-ignore-revs as this is a reformat commit.
Because of this change, unit tests were also reformated to use the
DB interface instead of sqlalchemy backend directly.
Test plan:
- PASS: Build a custom ISO with the changes and deploy a DX system
controller and a SX subcloud. Verify the system works as
expected.
- PASS: Manage a subcloud and verify the sync_status is "in-sync".
- PASS: Unmanage a subcloud and verify the management status was
updated to "unmanaged".
- PASS: Run "dcmanager subcloud show <subcloud_name> --detail" and
verify the output is correct.
- PASS: Run "sudo dcorch-manage db_clean 0" and verify old jobs were
successfully purged.
- PASS: Verify no errors were observed on dcmanager or dcorch logs.
